Abstract Dearomatization ability of ion exchange resins KU-2-8 and adsorbent Az-4, which developed on the basis of zeolitecontaining rocks in Azerbaijan, on the example of the virgin diesel fractions under the influence of a magnetic field was investigated. It was revealed that the investigated adsorbent Az-4 shows the identical activity with the industrial adsorbent KU-2-8. The influence of magnetic fields on adsorbent Az-4 and the adsorbent KU-2-8 results a decrease in the content of aromatic hydrocarbons almost in two times. Key words: dearomatization, adsorbent Az-4, resin KU-2-8, magnetic field influence, natural zeolites, adsorbtion.
1. Introduction Increasing of environmental pollution by motor transport and rise in the number of autoparks became the reason of requirement hardening of qualitative environmental characteristics of oil-refining industry products. Firstly, it concerns both qualities of fuels and combustion products. Emission autimobile gases with diesel engines contain carbon monoxide, sulphur, nitrogen, carbon-black, hydrocarbons and carcinogenic polycyclic hydrocarbons. On fuel combustion comprising sulphur admixtures it is obtained mainly sulphur dioxide. On content of ash elements (such as metal-containing additives) the part of sulphur transfers into sulphates and thrown up as solid particles. On combustion polyaromatic hydrocarbons there are obtaining carcinogens (benzpyrene, benz(a)anthracene, ovalen and etc.), which are the reason for many oncological diseases. Sulphur dioxide irritates respiratory apparatus, participates in obtaining of acid rain, in corrosion process, destructs catalyst converter. In connection with this the majority of modern standards limit sulphur content till 0.035% mass
